INJECTION MOLDED ARTICLES FROM NATURAL MATERIALS AND METHODS FOR MAKING

摘要

Injection molded articles and methods for making them from bio-based materials are described. More specifically, injection molded articles and methods for making them from bio-based materials that behave like high-molecular-weight thermosets such as lignin or protein-based materials including corn gluten meal, corn gluten feed, distillers dried grains with solubles, wet distillers grains, modified wet distillers grains, canola meal, wheat gluten, barley, cottonseed meal, sunflower meal, linseed meal, soy, rapeseed, sorghum proteins, maize, rice proteins, potato proteins, cassava proteins, sweet potato proteins, yam proteins, plantain proteins, keratin, or collagen are described.

1. A process for injection molding an article with a bio-based material comprising:
providing a mold, optionally heated; combining a bio-based material with an aqueous solution; introducing the hydrated bio-based material into an injection molding apparatus including a screw and barrel adapted for low shear; injecting the bio-based material into the mold; and compressing the material within the mold to form an article.
